Vertical draw system and method for surface adhesion of crystalline materials

A system of crystallization growth on a substrate surface of a substrate having a substrate material, the system comprising:

• a frame disposed in a chamber that provides an ambient temperature;
• a container having a reservoir therein;
• a sample holder to mount the substrate above the reservoir with the substrate surface facing a liquid surface of the reservoir;
• a sample holder temperature control device to control a temperature of the sample holder;
• a reservoir temperature control device to control a temperature of the reservoir independently of the temperature of the sample holder to produce a temperature difference between the substrate and the reservoir over a period of time for crystallization growth;
• and a linear stage to lower the substrate surface to the liquid surface of the reservoir and to retract the substrate surface from the liquid surface of the reservoir at a draw rate;
• wherein the draw rate and the temperature difference are selected to grow polycrystalline laminate on the substrate surface.

A computer program product for crystallization growth on a substrate surface of a substrate having a substrate material, which is mounted to a sample holder with the substrate surface facing a liquid surface of a reservoir disposed in a chamber that provides ambient temperature, the computer program product embodied on a non-transitory tangible computer readable medium, comprising:

• computer-executable code for, after the substrate surface is seeded with seed droplets, lowering the substrate surface to the liquid surface of the reservoir;
• computer-executable code for independently controlling the temperature of the substrate and the temperature of the reservoir to produce a temperature difference between the substrate and the reservoir over a period of time for crystallization growth;
• and computer-executable code for retracting the substrate surface from the liquid surface of the reservoir at a draw rate;
• wherein the draw rate and the temperature difference are selected to grow polycrystalline laminate on the substrate surface.
